Awesome investigation Ludo. This explanation could match what I was
experiencing when using the mysql service on GuixSD. Sometimes after
running guix gc, the system wouldn't boot. This could have been because
the guile package needed by the initrd was removed from the store.

Given that the initrd has a dependency on this guile, but it doesn't
reference it because its compressed, how about adding a explicit
reference to the guile used? I've attached a patch, and this looks to
fix the issue as far as the mysql service is concerned.
